I have managed to run Gmoccapy in Orange pi plus with 1 Gb Ram.
All working well.
I am addicted to Gmoccapy as it allow us to use physical buttons.

Hi,
 Raspberry Pi 4s are really not available now so I decided to try LinuxCNC on an OrangePi-PC 1GB H3

 I tried (on 2022-SEP-21)  several Armbian images, four of them were:
Armbian_22.08.1_Orangepipc_jammy_current_5.15.63.img.xz
Armbian_20.02.1_Orangepipc_buster_current_5.4.20_desktop.img
Armbian_20.08_Orangepipc_buster_current_5.7.15_desktop.img.xz
Armbian_21.02.3_Orangepipc_buster_current_5.10.21_xfce_desktop.img.xz

I did the following from an SSH terminal through putty:
sudo apt update
sudo apt upgrade
(Y, yes to all). Next I did:
git clone github.com/allwincnc/installer
cd installer
./install.sh
Used option 1: Allwinner H3
(Y, yes to all various prompts).
System Language:
0: Don't touch anything
Language Documentation:
1: English

Before rebooting I could see LinuxCNC Applications on the desktop.
Finally:
sudo reboot
and it hangs with a message regarding UUID=C8229.... does not exist
on the HDMI monitor. I cycle power and it still hangs with the same message.

Have I missed a step somewhere?  This message has shown up with different versions I've tried

Any guidance would be appreciated.

Thanks,
Jeff

I am using Armbian_20.05.1_Orangepipcplus_buster_current_5.4.43_desktop.img.
Also check the power source voltage. I have adjusted SMPS to 5.6 volts.
Below that my Orange pi also freezes.

Hi,
  Set the voltage to 5.65V.  No difference.
  I tried the version you mention, but its looking for the emmc (I think) when it reboots. Mine does not have emmc so no luck there.  I have tried the same version but for regular PC (not plus) and I get the freezing after reboot.

  Before rebooting, but after the update/upgrade/install, I can find through fstab:UUID=6ac4d9e0-4d0c-427c-a164-259d46a5ed28 / ext4 defaults,noatime,nodiratime,commit=600,errors=remount-ro 0 1
  but, once rebooting it gives the message that it can't find the UUID=6ac... (on this particular uSD).

  Even the debug UART stops working, so not sure (except if I hit the space bar at a particular point while it tries to reboot, I get to some shell I totally unused to).

  Anyway, any more suggestions would be appreciated.
Thanks,
Jeff

There's a silent first boot process on Armbian installs that resizes the root partition to fill the entire SD card. Sometimes that takes a good 5 to 10 minutes, let it sit and see if it finishes after some time.
if you've already booted an Armbian SD card that seemed to get stuck during first boot and you force powered the machine off then you probably want to re-flash the card before trying to boot again. It's possible to corrupt the root fs a bit if you power off during that resize process.
One more thing, Boot the image:-
sudo armbian-config
set the CPU min and max frquencies, reboot.
After this try to install linuxcnc

"set the CPU min and max frequencies" they should be the same number/value since you don't want the speeds changing over temperature or load since this introduces latency spikes.

Does Armbian warn the user in big red letters about the 5-10 minute first boot "stuck" time?

Hi,
   I've followed the first boot process after the update/upgrade/install process.  It does come to the resize and has an asterisk (iirc) going back and forth between the [ and ].  It finishes quick enough and continues.  I'll watch again and see if it gives any specific information that might be useful before it continues the process.

Thanks.

Hi,  The resize did happen in the initial deployment of the armbian system right after the putting the uSD in the OrangePi after running the Raspberry Pi Imager (v1.7.3), and I found no problems there. It was rather quick as well (20 to 30seconds perhaps).  It always stop with:
ALERT! UUID...... does not exist.  Dropping to shell!
(initramfs)
but from there is is dead on both the debug UART and the USB/HDMI interface.
